Acids and Bases

By JF & DCSize does matter

Recognizing Acids

• There is an H in front…ex. HCl• Acids taste sour• When reacted Acids give their H+• pH less than 7 (pOH greater than 7)• Burn rural bad when come in contact with

Recognizing Bases

• Create an OH- • ex… NaOH• Taste bitter• Bases take H+’s to make H2O• Feel Slippy• Form salts when reacted with acids• pH higher than 7 (pOH less than 7)

Common Acids• HCl– Hydrochloric Acid

• H2SO4– Sulfuric Acid

• HNO3– Nitric Acid

• H3PO4– Phosphoric Acid

• H2CO3– Carbonic Acid

Common Bases• NaOH– Sodium Hydroxide

• KOH– Potassium Hydroxide

• NH3– Ammonia

• CH3NH2– Methylamine

• C18H21NO3– Codeine

H20…

Both

Figuring pH and pOH

• Have pOH, do… 14-pOH=pH

• Have [OH-], do… -log[OH-]=pOH

• Have [H+], do… -log[H+]=pH

• 1.0x10-14=[H+]x[OH-]

How Acids and Bases React w/ Water

• With Acids-– Acids relinquish H+ to water to make H3O

• With Bases-– Bases take water’s H+ for its own and makes an

OH- left over

ICE Tables

Setting up an ICE table…Calculate pH of 0.20 M solution of HF (Ka=7.2 x 10-4)

HF + H2O = H3O + F-

INITIALCHANGE

EQUALIBRIUM

pH= 1.92

Equivalence Point

False or True

• John William Fisher is good looking?• David Wesley Christianson wishes he was as

good looking as John William Fisher?• Fer real now…

• The Equivilance Point falls anywhere between 6.0-8.0 pH?

False/True

• Bases are above 7 on the richter scale?

• Bases are Slippy?

• At EQ, H is greater than OH?

• pH and pOH are inverse of each other?
